She knows that you had once set off in a similar search and had come back with empty hands. She understands. She tries to understand, at least. Yes, even if with a pang. But then, that should not mean she has to make up for all that happened. Worse, that does not tell her that you aren't yourself a mirage now.
The Mirage says, as mirages are always known to say, that it's not so. It is not a mirage. It is only that it is just not-yet, it is just another few steps away. It is just asking of her that she be some more patient, some more perseverant, some more sensitive, some more sensible, practical, reasonable, logical.... damn!
You are a mirage. You better be! Because, she gives up here, and she does not want to find out later that you were what you claim you are when she, finally, now takes back her trust. Go to hell!
PS: She told you, didn't she, that she was tired of waiting? That she has just waited all her life? That she could live with suffering, but not with waiting any longer? Yes, she is selfish. She has tried to run away from herself in a desert, for too long to even remember what she was like when she was once alive. She better learns to be selfish this once. Forgive her!
PPS: Stay away. You must know that she will give up her resolve and get on her knees once more, if you don't.
